appiication sied July 24, 1914. serial No. 852,871.

T all whom it may concern.'

Be it known that we, JUDGE PECK Law- RENsoN and CHARLES HAsTiNGs KING, citizens of the United States, residing at Palestine, in thecounty of Anderson and State of Texas, have invented a new and useful Tire Tightener or Expander; and We do of the invention to provide a pair of plates,

one dis osed adjacent each severed end of a felly o a wheel, and provided with a right and leftthreaded member havingmthreaded connections with said plates, so that* they may be separated, for expanding the felly tight against the tire.

One of the features ofthe invention is to n construct these plates or cut them from stock metal bars of the requisite width and thickness, and'by the use of a cold chisel or otherl tool, the corners adjacent the outer faces of said plate are struck up to engage the Isevered ends of the felly as shown in the drawings, to'prevent displacement of said plate. Another feature of the inventionl is the provision of means comprising two interlocked plates engaging recesses of the adj acent faces of said plate and designed to engage a nut of the right and left' threaded member, to prevent it unscrewing after having been once adjusted. These interlocked platesralso vassist in preventing said plates adjacent severed ends of the felly from displacement. i

In practical fields the details of construction may necessitate alterations, falling withinthe scope of what is-claimed.

.The invention comprises further features and combination of parts,- as hereinafter set` forth, shown in the drawings 'and claimed.

In the drawings rr-Figure 1 is a View in side elevation of a portion of a felly showing a section having been cut away, and the tire tightener or elly expander disposed between and adjacent 'the severed ends `of the felly, and illustrating the means to prevent the right and left threaded member from'unscrewing. Fig. 2, is a vertical sectional view. Fig. 3 is a vdetail view of one of the severed ends of the felly, showing one of .said plates in a` position ready to be placed in contact with the severed end, showing the chisel cut orstruck up corner lugs,

in order to illustrate how said lugs are to engage said felly to prevent displacement of the plate. Fig. 4 is a detail View illustrating the interlocking plates, which are used for preventing unscrewing of the right and left threaded member.

pander or tire Ytightener, and showing the interlocking plate dispensed with.

Referring more especially to the drawf ings, 1 andy 2 designate the severed ends of the' felly 3, and 4 ldenotes the usual tire.

Therfelly expander comprises two plates 5 and 6, the corners of the outer faces of which are cut or struck up by means of a cold chisel, to form the lugs 7, which pierce or engage the severed ends of the felly in the manner illustrated in the drawing, to

prevent displacement of said plate. The plates 5 and 'are provided with threaded openings 9, and arranged between the plate is a rectangular member 10, projecting from opposite faces of which are threaded Shanks 11, which are alined and designed to engage said threaded openings. The threads of said`.-'shanks are right and left, and it will be observed that by the rotation of the rectangular member in one direction vor the other, said lplates 5 and 6 will separate, thereby causing the felly to expand, and

The adjacent faces of the plates are provided with oppositely arranged transverse recesses 12, Vand interposed betweenV said plates are plates 14 .and 15, the ends 16 of which engage said recesses 12. The plate 15 at one end is provided with forks 17, between which, the plate 14 is received. The inner face' of one of the forks 17 'is provided with teeth 18, which are engaged by the teeth 19 of the plate 14. ln connecting the two plates 14 and 15, in order to fit between said plates 5 and 6, the plate 14 slides transversely ofthe plate -15, the teeth 18 and 19 registering and engaging one another. Wheh placing the plates 14 and 15 in position, the plate 15 engages one or the other of the flat faces of the rectangular member, thereby preventing its unscrewing, after having been adjusted. In Fig. 5 the plates 14 and 15 are dispensed with, otherwise the structure is the same as shown 1n Y the other gures.

chiseled or struck up forming lugs to engage each severed end to prevent displacement of each plate, a rectangular member arranged between said plates having oppositely disposed alined right and left threaded shanks engaging said threaded openings, whereby upon rotating said member in one direction or the other said plates are separated to eX- pand the felly against the tire, the adjacent faces of said plates having oppositely arranged recesses, a second pair of plates having adjustable connections engaging said recesses and disposed adjacent and against one of the fiat faces of said rectangular member to prevent the same from unscrewing.

In testimony whereof we have signed our names to this specification in the presence of two -subscribin Witnesses.
